IOS 获取系统信息

IOS-获取Model（设备型号）、Version（设备版本号）、app（程序版本号）等

// app名称

NSString *app_Name1 = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleDisplayName"];

NSString *app_Name = [NSString stringWithFormat:@"%@",[[NSBundle mainBundle] objectForInfoDictionaryKey:(NSString *)kCFBundleNameKey]];

NSString *app_Name2 = [NSString stringWithFormat:@"%@",[[NSBundle mainBundle] objectForInfoDictionaryKey:(NSString *)kCFBundleExecutableKey]];

NSLog(@"==============1%@-----%@---%@",app_Name1,app_Name,app_Name2);

// app版本

NSString *app_Version1 = [NSString stringWithFormat:@"v%@",
[[NSBundle mainBundle] objectForInfoDictionaryKey:(NSString*) kCFBundleVersionKey]];

NSString *app_Version = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleShortVersionString"];

NSLog(@"==============1%@---%@",app_Version1,app_Version);

// app build版本

NSString *app_build1 = [NSString stringWithFormat:@"v%@",
[[NSBundle mainBundle] objectForInfoDictionaryKey:(NSString*)kCFBundleVersionKey]];

NSString *app_build = [[NSBundle mainBundle] objectForInfoDictionaryKey:@"CFBundleVersion"];

NSLog(@"==============1%@---%@",app_build1,app_build);

//ios获取系统信息

//NSLog(@"identifier: %@", [[UIDevice currentDevice] identifierForVendor]);

//NSLog(@"name: %@", [[UIDevice currentDevice] name]);

//NSLog(@"systemName: %@", [[UIDevice currentDevice] systemName]);

//NSLog(@"systemVersion: %@", [[UIDevice currentDevice] systemVersion]);

//NSLog(@"model: %@", [[UIDevice currentDevice] model]);

//NSLog(@"localizedModel: %@", [[UIDevice currentDevice] localizedModel]);
